Buckle



May 10, 1932. I sT. PIERRE BUCKLE Original Filed June 24, 1931 Patented May 1932 UNITEIDVSTATES PATENT. OFFICE HENRY ST. PIERRE, OF WORCESTER, MASSACHUSETTS BUCKLE Application filed J'ime 24, 1931, Serial No. 546,459. Renewed October 7, 1931. i

This invention relates to a holding device for a strap and is particularly adapted for use on a strap for a. cross chain or mud hook for an automobile tire. I The principal objects of the invention are to reduce the buckle or holding device to its simplest terms and to make it of a single sheet of metal, preferably flat, requiring no machine work and affording all the holding surfaces necessary to secure the strap to it and distribute the strain among a plurality of surfaces.

Other objects and advantages of the invention will appear hereinafter.

of sheet metal made flat and plain. It has a' Reference is to be had to the accompanying drawings, in which Fig. 1 is a plan of a single mud hook and buckle constructed in accordance with thisv invention; v

Fig. 2 is a plan of the buckle by itself; Fig. 3 is an edge view thereof; 7 Fig. 4 is a view like Fig. 1 showing the invention applied to a double mud hook, and

Fig. 5 is a plan of the buckle modified for connection with two chains, being the same as that shown in Fig. 4.

In Figs. 1, 2 and 3 I have shown this invention in its simplest form suitable for holding a single chain 10 of a mud hook or the like, this chain having a fastening buckle 11 on one end and a hook 12 on the other.

The buckle 13 itself is formed of a piece loop portion 14 around it at one end into which the bent ends of the hook 12-are adapted to engage as shown in Fig. 1. At the other end it has a straight bar 15 and it has two intermediate bars 16 and 17, all extend.- ing all the way across the buckle.

The canvas or other flexible strap 18 to be held by it is passed upwardly through the space between the bars 15 and 16 over the bar 16 and then downwardly and all the way around'the bar 17 and back over the bars 17 and 16 respectively and then down over the strand previously described, and in contact with the bar 15. The end of the strap is permanently secured to the strap itself at a point beyond the bar 15 by means of a rivet 19 or the like, near the end bar. This furnishes a very'strong holding means in which the friction of the textile material, of which the strap is made, is exerted between two layers thereof over 'a bar 16 to distribute the strain.

In use, this part of the device is held, of course, in as flat a conditionas possible so that the bar 15 is forced down against the upper mentioned lost because there is no position for the parts of the strap to assume under strain except the one illustrated and dea scribed.

Substantially the same conditions apply when this article is used for a double chain construction as shown in Figs. 4 and 5. Here the loop 14 is eliminated but two eyes 20 are used, forming a part of the body 21 of the buckle. The bars 15, 16 and 17 are in the same position as in the other figures and perform exactly the same functions. The locking or binding buckles 11 and 22 are not described in detail as they do not constitute a part of this invention. v

Although I have illustrated and described only two forms of the invention I am aware of the fact that other modificationscan be made therein by any person skilled in the art without departing from the scope of the invention as expressed in-the claims. Therefore I do not wish to be limited in this respect but what I do claim is 1. As an article of manufacture, a flat plain buckle for holding the end of a strap comprising a straight bar at the end and two insitely offset from the bars for recelving two chalns.

2. As an article of manufacture, a buckle having three bars'for holding the end of a strap, the buckle extending outwardly at both sides and having opposite attaching means on said extensions.

3. As an article of manufacture, a buckle for holding the end of a strap comprising three parallel bars, each extending all the way across the buckle, the body of the buckle extending outwardly at bothsides and having a pair of attaching means oppositely offset from the bars.

In testimony whereof I have hereunto affixed my signature.

HENRY ST. PIERRE.
